Description

This product was prepared from monospecific antiserum by immunoaffinity chromatography using Sheep IgG coupled to agarose beads followed by solid phase adsorption(s) to remove any unwanted reactivities, pepsin digestion and chromatographic separation. Assay by immunoelectrophoresis resulted in a single precipitin arc against anti-Donkey Serum, Sheep IgG and Sheep Serum

Store vial at 4C prior to opening. This product is stable for several weeks at 4C as an undiluted liquid. Dilute only prior to immediate use. For extended storage aliquot contents and freeze at -20C or below. Avoid cycles of freezing and thawing.

Applications for Donkey F(ab')2 anti-Sheep IgG (H+L) Secondary Antibody (Pre-adsorbed)

Application
Recommended Usage

ELISA

1:20000 - 1:100000

Immunohistochemistry

1:1000 - 1:5000

Immunohistochemistry-Paraffin

1:500-1:1000

Western Blot

1:2000 - 1:10000
Application Notes
This product has been tested by dot blot and SDS-PAGE and is suitable for immunomicroscopy and flow cytometry or FACS analysis as well as other antibody based fluorescent assays requiring extremely low background levels, absence of F(c) mediated binding, lot-to-lot consistency, high titer and specificity. The maximum amount of reagent required to stain 1 x 10E6 cells in flow cytometry is approximately 1.0 ug of antibody. Lesser amounts of reagent may be sufficient for staining. Optimal titers for other applications should be determined by the researcher. As a general guideline dilutions of 1:100 to 1:250 should be suitable for most applications.

Background: IgG (H+L)

Antibodies, also known as immunoglobulins (Igs) are critical for immunity and are grouped into five primary classes: IgG, IgM, IgA, IgD, and IgE. The most abundant antibody isotype is immunoglobulin G (IgG) with concentrations ranging from 7.5-22 mg/ml in human serum and has a molecular weight of 150 kDa. The major effector functions of IgG include neutralization, opsonization, complement fixation and antibody dependent cell-mediated cytotoxicity (ADCC). This monomeric immunoglobulin, expressed on the surface of mature B cells, is often depicted as a Y-shape and comprised of 2 heavy chains and 2 light chains linked by disulfide bonds. The heavy chain is type gamma including subtypes gamma 1, gamma 2, gamma 3, and gamma 4 while the light chain is either a kappa or lambda chain. An IgG molecule has two antigen binding sites, each consisting of a heavy and light chain N-terminal variable domain. When combined with the constant heavy chain 1 (Ch1) and the constant light chain domains, it forms the fragment antigen-binding (Fab) region (2 per antibody). The remaining domains (Ch2-Ch4) of both heavy chains make up the Fc region and contain a site for covalently linking an enzymatic or fluorochrome probe, such as HRP or Janelia Fluor 549, for target detection and visualization (1,2,3).

The 4 IgG subclasses, sharing 95% amino acid identity, include IgG1, IgG2, IgG3, and IgG4 for humans and IgG1, IgG2a, IgG2b, and IgG3 for mice. The relative abundance of each human subclass is 60% for IgG1, 32% for IgG2, 4% for IgG3, and 4% for IgG4. In an IgG deficiency, there may be a shortage of one or more subclasses (4).
